Thanks to Veronica for sending in these fantastic photos of a Poplar Hawk-moth resting on a wall in West Somerset. You can see its characteristic repose, with abdomen curved into the air and hind-wings swung ahead of forewings.

The second picture below gives a brilliantly detailed look at the unusual wing geometry from the side. I also love the way the antennae curve back around like the arms of sports sunglasses. Click for higher resolution versions of each image.
